Description

Process for the production of multi-use strips and their use

The invention relates to a method of making a multi-benefit strip intended for application to a target substrate, further relates to the multi-use strip and relates to the corresponding use for application to the target substrate.

Data carriers, such as valuables or identity documents, but also other valuables, such as branded articles, are often provided with security elements for the purpose of security, which permit verification of the authenticity of the data carrier and at the same time serve as protection against unauthorized reproduction. Security elements may for example be integrated into the substrate of the data carrier or applied to the substrate of the data carrier.

Various methods are known for applying a single security element in a positionally accurate manner to a single data carrier.

On a multiple benefits, such as a banknote sheet that includes multiple individual benefits, a multi-use strip can be applied, on which several security elements are arranged one behind the other. The position of the multi-use strip for multiple use is irrelevant in many applications. In some cases, however, a positionally accurate application is sometimes desirable. In EP 2 848 425 A2 it is proposed to create several security elements one behind the other and from one another on an endless track as an intermediate carrier. The security elements are thus created in exactly the form in which they are to be applied to a target substrate.

In alternative solutions, a created area is brought into the outer shape of the security element either before application and / or when applied to the target substrate. The invention has for its object to provide a flexible method, which ensures in particular a good positioning.

This object is solved by the features of the independent claim. Further developments of the invention are the subject of the dependent claims.

The present method for producing multiple-use strips comprises at least the following steps. Multi-utility sections are created on an intermediate carrier, with the multi-utility sections being provided for application to a multi-utility area of a target substrate. For each multi-use section, two outer sections are created on the intermediate carrier, which are provided for application to outside areas of the target substrate. The two outer sections of a multi-use section together with the multi-use section a Mehrnutzenstreifen. The outer portions of the multi-utility strip are prestructured on the intermediate carrier for application of the multi-use strip to the target substrate. The intermediate carrier is an intermediate carrier web, on which several of the multiple-use strips are created side by side. The subcarrier is cut into several strip enteilbahnen on which in each case several of the pre-structured multiple-use strips are arranged one behind the other in length.

The multiple-use strip can furthermore be transferred to the target substrate using a conventional device. A possible positional accuracy in the pre-structuring does not have a negative effect on the positioning of the multi-use section.

In addition, pre-structuring in the outer section avoids that the multi-use section is impaired by the pre-structuring. For example, mechanical pre-structuring can lead to deformations, optical pre-structuring by means of a laser, for example, premature thermal activation of a pressure-sensitive adhesive, and chemical pre-structuring, for example, by diffusion effects into the multiple-use section.

The fact that the pre-structuring takes place before the intersection of the intermediate carrier web in strip enveys has several advantages, which will be dealt with individually below.

Preferably, pre-structuring takes place longitudinally offset from one another for multiple-use strips lying next to one another on the intermediate carrier web. Due to the offset of the pre-structuring, it is possible to spatially distribute (and thus locally reduce) a possible, in particular mechanical, load on the intermediate carrier web which is triggered by the pre-structuring.

The outer portion preferably comprises a Mimmalabschnitt which is applied to the target substrate, and a Vorstrukturierungsabschnitt. For two (adjacent or) successive multi-use strips can lie between two outer sections, in particular between the two Vorstrukturierungsabschnitten, an intermediate area.

A pre-structuring offset is possible regardless of the position of the multi-use sections on the intermediate carrier track. For example, the multi-use sections lying next to one another can be present without offset (identical) to one another on the intermediate carrier track. The location of the pre-structuring may vary within the pre-structuring section (and / or the intermediate area). Alternatively or additionally, the length of the minimum sections may be varied to obtain a pre-patterning offset.

Particularly preferably, at least the adjacent multi-use strips are created longitudinally offset from one another. A multi-slot offset on the subcarrier may contribute to a pre-patterning offset, thus creating or increasing it.

If the adjacent multi-utility strips are prestretched offset, the Vorstrukturierungsversatz is preferably greater than 4 mm.

The application of the Mehrnutzenstreifen on the target substrate is done with a position tolerance. This position tolerance depends on the device used, it is usually between 0.5 to 1 mm, but in any case less than 2 mm. The position tolerance indicates the maximum deviation of the actual position of the multi-use strip on the target substrate from a reference position, ie the position of the multi-use region. Preferably, the pre-structuring offset is greater than twice the position tolerance. In particular, the minimum section is preferably greater than twice the position tolerance. In the present case, a pre-structuring tolerance may be greater than the position tolerance. The size of the pre-structuring tolerance has no influence on the positioning tolerance by the present solution. In the pre-structuring can therefore be worked cheaper or with less control effort.

In preferred embodiments, the intermediate carrier web comprises a primary carrier and a secondary carrier. The secondary carrier is usually laminated to the primary carrier. An advantage of this embodiment is that it is possible to change only the secondary carrier in the step of pre-structuring. The primary carrier is not detected by the pre-structuring. A laminating adhesive layer preferably has a thickness of 2 to 3 μm.

In one embodiment, the primary carrier is thus laminated onto the secondary carrier (on the back of the secondary carrier) before the step of pre-structuring the multiple-use strips. In particular, if the pre-structuring is effected by means of laser radiation, it is conceivable to protect the primary carrier by means of a non-laserable barrier layer, for example a copper layer, which is provided between primary carrier and secondary carrier.

In a particularly preferred embodiment, the primary carrier is laminated on the secondary carrier (on the back of the secondary carrier) only after the step of pre-structuring the multiple-use strips. This configuration increases the flexibility in the pre-structuring and guarantees the required stability. Depending on the requirements, different primary carriers can be laminated and / or pre-structured differently. The primary carrier web is laminated to the back of the secondary carrier web, the lamination is thus carried out before cutting the intermediate carrier. In particular, the subsequent lamination, possibly in conjunction with an offset, pre-structuring, which cut, remove or cut the primary carrier (and the Mehrnutzenstreifen) over the entire width of a strip of partial web. In the pre-structuring step, the exterior section created is prestructured in particular mechanically, chemically or by irradiation. The pre-structuring corresponds to a local or regional change of the created outer section. As a rule, the pre-structuring extends over the entire width of the strip partial web (or over the length of Vorstrukturierungsabschnittes). It can in particular serve to avoid contamination, for example by fragments of the multi-use section, as it is currently known for multi-use sections with embossing lacquer layers. Likewise, however, the pre-structuring may also be useful in order to support a reliable application to the target substrate, in particular if otherwise adhesion problems could arise during the release of the intermediate carrier from the multi-use section. Lasering, UV irradiation and / or (ultra) sound-based methods are conceivable in particular as irradiating pre-structuring. Mechanical prestructuring may include perforating, punching, punching or pressing. A chemical pre-structuring may include local removal (etching) or local modification (eg, locally softening brittle embossing lacquer). The pre-structuring can take place as a single pre-structuring, as pre-structuring repeating in a partial area, or as a pre-structuring uniform or repetitive throughout the pre-structuring section be designed. Likewise, pre-structuring may extend over a partial surface or the entire surface of the pre-structuring section, in particular in that a continuous pre-structuring continues in a pattern-like or meandering manner over the partial surface or the entire surface.

Particularly preferably, outer sections of two adjacent multiple-use sections are prestructured together. In particular, these two outer sections may comprise a common pre-structuring section. Alternatively, there are two separate pre-structuring sections and optionally an intermediate section, with the pre-structuring sections (and the intermediate section) being pre-structured jointly and uniformly.

Advantageously, in the step of creating the outer sections in at least one of the outer sections, a positioning aid for positioning the multi-use section to the target substrate and / or a production identifier is created which uniquely identifies the multi-use strip, the strip partial web and / or the intermediate carrier web. If the positioning aid is created together with the multi-benefit section, and not independently of the pre-structuring, for example, no additional tolerances are created. A production identifier uniquely identifies the multiple-use strip, the strip strip track and / or the intermediate carrier strip, at least in the production system. It can thus be detected and stored which components have been processed or which component is at least partially contained in which end product, such as banknote.

The created multi-use section is a multi-layer construction comprising at least three partial layers. In particular, the multi-layer Build at least three of the following sub-layers: first embossing lacquer layer second embossing lacquer layer, reflector layer, protective layer, release layer and / or adhesive layer. The multi-utility strip fabricated by the present method is used for application to a target substrate such that the multi-utility section is on a multi-utility area of the target substrate and the exterior sections are on an exterior of the target substrate. In particular, multiple multi-use strips with optionally different lengths of outer sections can be applied to the target substrate. In a subsequent step, the intermediate carrier is released from the applied Mehrnutzenstreifen. By cutting the multi-use area of the target substrate with the applied multi-use strips, the individual benefits can be generated.

Further exemplary embodiments and advantages of the invention are explained below with reference to the figures, in the representation of which a representation in terms of scale and proportions has been dispensed with in order to increase the clarity.

Strip partial web in supervision, an intermediate carrier web with a plurality of offset arranged Mehrnutzenstreifen on strip enteilbahnen; an intermediate carrier web on which only adjacent Mehrnutzenstreifen are offset from each other; an intermediate carrier web with unused arranged multi-use sections with staggered pre-structuring; a cross section for the substrate with applied strip as a single use; a cross section through a two-layer intermediate carrier with Mehrnutzenstreifen and punched secondary carrier; a cross section through an intermediate carrier with Mehrnutzenstreifen and Vorstrukturierung; and a strip sub-web with position aid in the outer section.

FIG. 1 shows a target substrate 10 with multiple-use strips 20 already applied thereto. Starting from the example of a banknote as a product, the target substrate 10 is a banknote substrate sheet and the multi-utility strip 20 is a security strip for a plurality of banknotes.

The target substrate 10 comprises a multi-use region 12 and an outer region 16. The multi-use region 12 is defined as one Variety of individual benefits 14. The length of the multi-use range LI 2 corresponds to a multiple of the length L14 of single-use. Shown is a multi-utility area with four times four individual benefits. The outer region 16 surrounds the multi-use region 12. For example, a banknote arises later from each individual benefit.

Four multi-utility strips 20 are applied to the target substrate 10. Each multiple-use strip 20 rests on the multi-use area 12 with four single-use 14 and on the outer area 16. The length of the Mehrnutzenstrei- fens L20 is deliberately greater than the length L12 of the Mehrnutzenbereiches 12th

The individual sections and associated lengths of the Mehrnutzenstreifens are shown in more detail in Figure 2.

FIG. 2 shows a plan view of two multi-use strips 20 and 20A which are still arranged on an intermediate carrier (not shown in the figure because they are located below it). The multiple-use strip 20, 20A comprises a multi-use section 21, 21 A and on each side an outer section 22, 22A. The multi-use section 21 is between its two outer sections, of which in Figure 2, however, only one, the right outer portion 22 of the Mehrnutzenstreifens 20 and the left outer portion 22A of the Mehrnutzenstreifens 20 A, is shown. In terms of its length L21, the multi-use section 21 corresponds to the multi-use area of the target substrate (L21 = L12) to which it is to be applied.

The two outer sections are - at least partially also applied to the target substrate, namely on the outside of the target substrate, together with the multi-use section. The length of the applied Mehrnutzenstxeifens is thus composed of the length of the

Mehrnutzenabschnittes and the length of the two outer sections. For example, if both outer sections are the same length, then L20 = L21 + 2 * L22. If both (right and left) outer sections are of different lengths, then L20 = L21 + L22_links + L22_right.

Between the outer portions 22 and 22A of two successive multiple-use strips 20 and 20A, an intermediate region 23 may optionally be provided which is not provided for the target substrate (not applied).

Pre-structuring can take place on the intermediate carrier with different means and with different effects. The pre-structuring prepares the multi-use strip for application to the target substrate.

A pre-structuring 24 may, as seen in Fig. 2, limit the outer portion 22. By limiting Vorstrukturierung an outer portion 22 is formed on the intermediate carrier, which is to be applied with its predetermined length L22 on the target substrate.

The outer portion on the intermediate carrier may be divided into a minimum outer portion 26 to be applied with its length L26 to the target substrate, and a Vorstrukturierungsabschnitt 27. The pre-structuring 24 can now be arranged, optionally at an arbitrary position, within the pre-structuring section 27.

The length L22 of the outer section is in the range:

L26 <L22 <L26 + L27. If the pre-structuring 24 is a (length-) limiting pre-structuring, the position of the pre-structuring 24 in the pre-structuring section 27 determines the length of the outer section L22 to be applied. For example, the pre-structuring 24 could be done by removing lasing of the multi-layer structure created on the subcarrier. In other examples, the pre-structuring takes place mechanically, chemically or with other (non-laser) irradiation, in particular by changing and / or removing. The multilayer structure may be locally pre-structured only at the edge of the outer portion 22, in the example: removed, or prestructured (eg removed) over an entire area that ends at the edge of the outer portion 22.

However, a pre-structuring 24 on the intermediate carrier can also be configured (length-variable) pre-structuring. By means of a variable pre-structuring in the pre-structuring section 27, the multiple-use strip 20 with an outer section L22 can be applied to the target substrate whose length L22 is determined only during application. The variable pre-structuring 24 extends over the pre-patterning section 27 (of length L27).

On the intermediate carrier, the variably pre-structured multi-use strip 20 is present as a minimal multi-use strip 25 with a longitudinal length L25 (L25 = L21 + L26). Only when applying the multi-utility strip 20 to the target substrate, the actual length of the applied Mehrnutzenstreifen or the outer portion 22 is set. As a result of the variable prestructuring, the minimum outer section 26 is always applied and the pre-structuring section 27 is applied with a variable length, that is to say it is applied only in part. A variable prestructuring can be achieved, for example, mechanically, by full-surface perforation, full-surface and possibly randomly distributed punching or other over the section extending or full surface mechanical treatment can be achieved. Similarly, by irradiation, for example, a perforated surface or a portion may be created which is patterned, possibly randomly distributed, removed or altered. It is also conceivable to treat the pre-structuring region chemically over the entire surface or in a distributed manner so that, for example, an embossing lacquer does not harden or re-soften (under UV light).

In particular embodiments, a uniform Vorstrukturierung 24 ranges from the outer portion 22 of the Mehrnutzenstreifens 20 to the outer portion 22A of the Mehrnutzenstreifens 20A. This uniform pre-structuring can be a predetermined pre-structuring or a variable pre-structuring.

In FIG. 2, the two adjacent pre-structuring regions 27, 27A, together with the optional intermediate portion 23, are designated as preparation section 28. The preparation section 28 has a length L28, where 2 * L27 <L28 <2 * L27 + L23. Alternate (not pre-structured) minimal additional use strips 25 and pre-structuring preparation sections 28 are thus arranged on the intermediate carrier. This subdivision will continue to be used in the next figures, which primarily consider the local distribution of pre-structuring on an intermediate carrier sheet.

In the ideal case, as indicated in FIG. 2 by the central position of the pre-structuring 24 in the pre-structuring section 27, half of the pre-structuring section 27 is also applied to the target substrate. By Positional tolerances during application may be the length of the applied outer portion L22, however, between the minimum length L26 and the sum of the minimum length L26 and the length of the Vorstrukturierung L27 (L26 <L22 <L26 + L27).

The position tolerance during application relates to the position of the multi-use section 21 to the location of the multi-use area. It depends on the device used, but is regularly between 0.5 to 1.5 mm. The position of the created multi-use section 21 and the position tolerance during application are independent of the pre-structuring in the present solution. Consequently, an inaccuracy or tolerance in pre-structuring (pre-structuring tolerance) does not affect the positional tolerance of the multi-use portion during application. The position of the pre-structuring 24 can vary randomly, in the sense of a pre-structuring tolerance, or-as explained with the aid of the following figures-can be deliberately varied.

FIG. 3 shows an intermediate carrier track 30 which comprises a plurality of strip sub-webs 32. The intermediate carrier web 30 preferably comprises at least four strip sub-webs 32. The illustrated sub-carrier web 30 further comprises optional control sub-webs 31, 33 and 35. On the strip sub-webs 32, minimal multiple-use strips 25 and preparation sections 28, including pre-structuring, are arranged. The preparation section 28 preferably comprises, for example, two pre-structuring and an intermediate section or a continuous pre-structuring. The strip partial webs can be configured as already described with reference to FIG. The strip sub-webs 32A, 32B and 32C are juxtaposed on the intermediate carrier web 30. In the strip sub-web 32A, from left to right, a first preparation section 28, a minimum utility strip 25A, a second preparation section 28 and an adjacent minimum utility strip 25B can be seen.

As indicated in the multi-utility strip 25A, the multi-use section comprises a three times - corresponding to the number of individual benefits -repeating motif (star, cross, star). The motif is a security element and can be provided, for example, as a hologram, as an optically variable element and / or on the basis of a coated relief structure. The motif-free outer portion is indicated in the figure only by the distance of the first star of the motif to the preparation section 28. The further strip sub-webs 32, 32B and 32C also comprise a plurality of successively located Mehrnutzenstreifen which are arranged between preparation sections. The repeated presentation of the motif was omitted in favor of the recognizability of the other aspects shown. Starting from an intermediate carrier track 30, the multi-use sections and the outer sections of the multiple-use strips are created on the intermediate carrier. The minimum multi-utility strips 25 A, 25 B each comprise a multi-use section and two outer sections. The minimum multi-utility strip 25 is provided - in its entirety - for application to the target substrate. The multi-use section is later - as described for Figure 1 - applied to the Mehrnutzenbereich and the outer sections on the outer region of the target substrate. In the preparation area 28, the two outer sections of the multi-utility strip are pre-structured on the intermediate carrier web 30. On the intermediate Trägerba n 30 are several created Mehrnutzenstreifen (on the stripe sub-webs 32) side by side. The strip partial webs, as described for FIG. 2, are produced from the intermediate carrier web 30 by cutting the intermediate carrier web 30 into a plurality of strip sub-webs 32, on each of which several of the pre-structured multiple-use strips are arranged one behind the other.

3 shows an offset arrangement of the multiple-use strips 25A, 25B in the strip sub-webs 32A, 32B, 32C on the intermediate carrier web 30. The multiple-use strip offset also causes the pre-structuring sections 28 to offset one another on the intermediate carrier web 30. The offset is selected the pre-structuring sections of at least adjacent strip partial webs are not arranged overlapping. The pre-structuring offset distributes burdens, in particular of the sub-carrier, which can occur due to the pre-structuring. The distribution of the load can also increase the position accuracy during application. In addition, the offset allows additional forms of pre-structuring, such as punching out the entire preparation section. The offset does not affect the cut strip part webs 32 or their use, since they are identical in the sequence of the multiple-use webs.

The Vorstrukturierungen 28 are arranged, for example, evenly distributed over the length of the Mehrnutzenstreifens example. In particular, the multi-utility strip offset may be greater than half the single-use length (and less than twice the single-use length). On the intermediate carrier web 30, in particular on the control partial webs 31, 33 and 35, preparatory hip marks 311, 312; 331, 332, 334, 335 and 351, 352 may be provided. The preliminary hubs are used, at least in the prestructuring step, to determine the location of the pre-patterning (and / or its length and / or offset) to be performed. However, the preparatory hip marks may already be used for the step of (staggering) creating the multi-use strip. A preparation auxiliary marker 311 indicates the position for the preparation section 28 between the multi-utility strips 25A and 25B. A second auxiliary marker 312 may be provided to define the width of the preparation section 28 and / or the location of the second pre-patterning. Corresponding preparation auxiliary marker 331, 332 also contains the control partial web 33. With the aid of at least one further auxiliary preparation marker 333, 353, the multiple-use adhesive offset can be determined. The preparation auxiliary marker 333, 334 or 353, 354 also mark the position of the pre-structuring on the adjacent strip tuft 32 in the present case.

In the variant shown in FIG. 3, multiple-use strips of a plurality of strip webs are arranged offset from each other. Mehrnutzenstreifen AUer strip strips or at least three strip strips can be arranged offset from each other (or created).

FIG. 4 shows a simplified example of an otherwise analogous example in which only the multiple-use strips of adjoining strip sub-webs 32A, 32B and 32B, 32C are offset relative to one another. The Mehrnutzenstreüen the strip enteilbahnen 32A and 32C, however, are arranged without displacement. In variants not shown separately, the multiple-use strip offset may be smaller than the length L28 of the preparation section 28. The preparation sections of adjacent strip sub-webs on the intermediate carrier are then offset but overlapping (and not as shown in FIGS. 3 and 4 shown without overlapping) to each other.

Figure 5 shows a solution variant with staggered pre-structuring, without the multi-use sections must be created offset. The multi-utility portions 21A, 21B of the stripe sub-webs 32A, 32B, and 32C are made unmounted on the sub-carrier web. Only the pre-structuring of the multi-use strips on the intermediate carrier track 30 is offset. The preparation regions 28 (and thus the pre-structuring) of adjacent strip sub-webs 32A, 32B are arranged offset to one another. Due to the Vorstrukturierungsversatz varies the length of the minimum (and actually applied) outer portions 26A, 26B on the intermediate carrier web 30. For Mehrnutzenstreifen on juxtaposed strip portions 32 A, 32 B and / or for consecutively hanging Mehrnutzenstreifen a partial path 32 B are different lengths outer sections before.

If, for example, the pre-structuring in each case forms the boundary of the preparation region, the pre-structuring of juxtaposed strip sub-webs is also arranged without overlapping in the example shown. For pre-structuring present in wide or even uniform manner in the preparation area 28, on the other hand, the pre-structuring of the adjacent strip partial webs overlaps. The prestructuring offset and the width of the prestructuring section are preferably selected such that do not overlap the pre-structures of adjacent strip enteilbahnen.

A pre-structuring offset can-as shown in FIG. 5-be provided without multiple-groove staggering or alternatively also together with a multiple-use-staggering offset-corresponding to FIG. 3 or 4.

As a further option, it is shown in FIG. 5 that additional intermediate webs 39 can be arranged between the strip part webs 32A, 32B. The intermediate tracks 39 can have a stabilizing effect similar to the pre-structuring offset. The intermediate tracks 39 are - similar to the control tracks 31 - not needed and accordingly after the cutting of the intermediate carrier web 30 in strip enteilbahnen 32 disposed of. FIG. 6 shows a cross-section through a single end 14, for example a banknote, with a security element in the form of a single-use strip 620, which is applied to a (target) substrate. This single benefit 620 of a utility strip 20 comprises a multi-layer construction. The single-use strip 620 is attached to the target substrate by means of an adhesive layer 628 and includes, for example, a metal layer 626, an imprint layer 624 (with surface relief structure not shown on which the metal layer 626 lies) and an optional resist layer 622. As shown for the single-use strip 620, it may on a substrate coating 612 of the substrate, for example a continuous or structured printing layer or a continuous lacquer layer. Alternatively, as indicated for another single-use strip 620B, the single-use strip may be applied directly to the substrate body 610, in particular in a recess of a substrate coating 618. The substrate comprises a substrate body 610, which typically consists of paper, plastic or a hybrid composite (paper and plastic layers). Security elements 616 can be embedded in the substrate body 610. The single-use strips 620 and 620B may be arranged at least partially or completely overlapping. They can complement each other as security elements or with an embedded security element 616, in particular visually for the viewer.

As shown in FIG. 1, a plurality of multi-use strips can be applied to a target substrate (in particular simultaneously). Using the example of the two front and rear side on the substrate 610, 612,618 single-use strips 620 and 620B, it can be seen that multiple-use strips can be applied to the target substrate in FIG. 1 on the front and rear side (different depending on the page or similar). On the front and rear side applied Mehrnutzenstreifen can on a target substrate completely overlapping (congruent), partially overlapping (parallel to each other or crossing each other in each individual) or non-overlapping (congruent preferably parallel to each other) are arranged.

FIGS. 7 and 8 show two examples of cross sections through a two-layer subcarrier with multi-use strips created thereon and pre-structured.

According to the embodiment in FIG. 7, 733 consecutive multi-use strips 25 are created on a primary intermediate carrier (primary carrier). The multi-use strip 25 is formed by a multi-layer structure 721 realized until 727. Also in the preparation areas 28, a (motif-free) multi-layer structure is partially created.

The primary intermediate carrier 733 is still present as an intermediate carrier web and thus can be simply punched out in the size (of the pre-structuring section or) of the preparation section 28. After pre-structuring, a secondary carrier 731 is applied to the primary carrier 733 by means of an adhesive layer 732 on the rear side (laminated). The resulting from the punching holes in the intermediate carrier web (or carrier gaps in the strip enteilbahn) are thus closed again. Optionally, in the preparation section 28, a positioning aid 712, which assists positioning during the application of the multi-use section, can be created. The now two-layer intermediate carrier web with the pre-structured Mehrnutzenstreifen 25 is cut into strip partial webs.

The illustrated multilayer structure 721 to 727 of the multi-use strip comprises a release layer 721, a lacquer layer 722, a reflector layer 723, a dielectric layer 724, an absorber layer 725, an only optional intermediate foil 726 and an adhesive layer 727. The adhesive layer 727 serves to attach the further layers 722-726 on the

Target substrate and can be provided in particular as a heat sealing lacquer. The release layer 721 aids in peeling off the utility strip from the subcarrier when applied to the target substrate. The lacquer layer 722 may be provided as an embossing lacquer layer with an embossed relief structure. A relief for holograms, micromirrors, microlenses or sub-lambda structures can be embossed. The reflector layer 723 can serve as a reflector on the relief of the lacquer layer 722 and / or together with a dielectric layer 724 (constant or locally varying thickness). and an absorber layer 725 form an optically variable thin-film element.

FIG. 8 shows another embodiment of both the multiple-use strip and the pre-structuring.

The intermediate carrier is configured in two layers with a primary carrier 833 and a secondary carrier 831 laminated by means of adhesive layer 832. The multiple-use strips 25 including the multi-use section 26 and the outer section 21 are created on the intermediate carrier.

The multi-layer structure 821 to 826 of the multi-use strip comprises in the multi-use section 21 an optional release layer 821, a (first radiation-curing) lacquer layer 822, a (second radiation-curing) embossing lacquer layer 823, a reflector layer 824 (for example metal layer), an optional primer layer 825 (adhesion promoter ) and an adhesive layer 826. The function of the layers already discussed is not reproduced here. The second lacquer layer 822 below the unembossed side of the embossing lacquer layer 823 has proved to be advantageous for embossed relief structures. The reflector layer 824 forms together with the relief structure of

Embossing lacquer layer, the motif or the security element of the Mehrnutzenabschnittes.

In mirumalen outer portion 26 of the Mehrnutzenstreifens 25 no metal layer is arranged. The outer section is motif-free. In the minimal outer portion, therefore, the embossing lacquer layer 823 is generally unembossed, that is to say without a relief structure. The non-motivating layers 821, 822, 824, 825 and 826 are present in the outer portion as well as in the multi-use portion. Embossing lacquer layer 823 (and underlying layers 821 and 822) extend into the preparation area. In the preparation area, at least the embossing lacquer layer 823 is prestructured on both sides. The two pre-structurings 88 extend into the primary carrier 833. It is conceivable, but not necessary in the present embodiment to provide a plurality of pre-structuring side by side or to provide the section 28 with a plurality of Vorstrukturierungen. Without a secondary support 831, a strip part web with multiple-use strips could tear (positioning problem) or even tear in extreme cases. The pre-structuring 88 can be produced, for example, by perforation or incision in the corresponding depth, in particular by laser or mechanically. Positioning aids 82, 86 and a production identifier 84 can be seen in their position relative to the other layers in FIG. Their respective function will now be described with reference to FIG.

FIG. 9 shows-analogously to FIG. 2 -a strip partial web with a plurality of multi-use strips 20 in plan view. Therefore, only the additional elements are discussed.

In the outer portion 22, a positioning aid 86 can be created, which indicates the exact location of the multi-use section. The multi-utility section positioning aid 86 as well as an optional positioning aid 82 for the pre-structuring section 27 are prepared in the step of creating the outer section. By means of the positioning aids 82, the position of the pre-structuring can be defined for the step of pre-structuring. Thus, the (possibly different che) length of the outer sections 22 and the width of the intermediate sections 23 are generated or taken into account.

A production identifier 84 is a one-to-one identification, for example in the form of a number or a barcode. The production identifier 84 uniquely identifies the multiple-use strip, the strip partial web and / or the intermediate carrier web, at least in the production system. It can be automatically captured and stored when applying the multi-use strip or in a subsequent production step. On the basis of the collected data it is comprehensible which components have been processed or which component, such as single-use strips as a security element, in which end product, such as banknote, is at least partially contained.
